New research has revealed Brits are getting themselves into hot water for forgetting important dates or information.

According to a study of 2,000 people, one in five men have got themselves into trouble for forgetting important dates or information and one in ten blokes say they have forgotten their partner’s birthday.

The study found passwords are the most common pieces of information Brit’s are forgetting followed by where keys have been placed. A relative’s birthday was the third most common overlooked date and pin numbers came fourth in the list.

A friend’s birthday, remembering to pay a bill and where the car is parked were also fairly common things the nation is forgetting.

More than half of Brits said they would be upset about forgetting their partners birthday followed by 44 per cent who said they would be the most upset about forgetting their child’s birthday and one third said forgetting a relative’s birthday would be the worst thing for them to do.

A spokesman for Admiral Multicar, which commissioned the study, said: “As a nation, working hours are getting longer and social lives are getting busier. So it’s perhaps not surprising that many people are starting to forget passwords, deadlines and pin numbers.

“There are so many ways we can help ourselves remember things, the trick is to remember to use these first too. Phone reminders, calendars, diaries or even sticky notes – as long as you don’t forget the important things it doesn’t matter how you go about doing it.”

Three quarters of organised Brits said they try to use a diary or an events planner in order to remember any important dates coming up.

Men have been accused of being the most forgetful sex but 47 per cent of Brits think believed their memory is getting worse as they get older.

The spokesman added: ““It’s important not to beat yourself over the head if you forget something minor, and you can always learn from your experience. If you are organised in your life, you are less likely to forget important dates and events.”

“We commissioned this research because remembering the date of your insurance renewal is one of those things it’s easy to forget. With Admiral MultiCar you can add additional cars to the policy and then forget about them. They stay with their current insurer until that policy ends and the join the MultiCar policy. It’s just one less thing to think about.”
